Zhongtai New Energy ZT300 300W Polycrystalline Solar Panel

Model No. ZT300 | Polycrystalline | 72 Cell | Monocrystalline | 1000V System Voltage

300 Wp
Max Power Output
15.46%
Module Efficiency
72
Polycrystalline

Product Overview

The Zhongtai New Energy ZT300 is a reliable 300W polycrystalline solar panel built for steady energy production. It combines a 72-cell layout with durable construction for dependable long-term use. The module offers a 10-year product warranty and a 25-year power warranty, supporting confidence in its performance over time. With 15.46% efficiency, it suits projects that value balanced output and stable operation. Its robust frame, tempered glass, and broad operating temperature range make it practical for varied installation environments.

Key Benefits

Reliable 300W Output: The panel delivers 300Wp of maximum power for consistent daily energy generation.

Durable Construction: Tempered glass and an anodized aluminium frame help support long service life.

Strong Warranty Coverage: A 10-year product warranty and 25-year power warranty provide added buyer reassurance.

Wide Operating Range: The module is designed to perform across temperatures from -45°C to 85°C.

Easy System Planning: Its electrical ratings make it easier to match with common solar system designs.

How It Works

This polycrystalline solar panel converts sunlight into usable direct current electricity through its 72-cell module design. Each cell captures solar energy and contributes to the panel's total output under standard test conditions. The module produces power most effectively near its maximum power point, where voltage and current are balanced for stable generation. Its tempered glass front and EVA encapsulation help protect the cells while supporting consistent exposure to sunlight. The anodized aluminium frame adds rigidity and helps the panel remain structurally stable during installation and use. With a maximum system voltage of 1000V, the panel can be integrated into many standard solar arrays. Its electrical characteristics also support straightforward matching with compatible charge controllers, inverters, and system layouts.

Sunlight Conversion: The polycrystalline cells absorb sunlight and generate electricity for the connected system. Output is measured at 300Wp under standard conditions.

Electrical Performance: The module operates at 36.6V at maximum power and 8.2A current. These values help define compatible system design.

Protection and Structure: Tempered glass, EVA encapsulation, and an aluminium frame support protection and durability. This helps the panel stay dependable outdoors.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
